It never has -2 oxidation number.
Nitrogen oxidation numbers are possible: -3 (nitrides), 0 (elemental), +3 (nitrites), +5 (nitrates).
Also +1, +2 and maybe +4 are possible (in Nitro-oxides only).
In the compound NO, nitrogen (N) has an oxidation number of +2 and oxygen (O) has an oxidation number of -2. This is because oxygen usually has an oxidation number of -2 in compounds, and since NO is a neutral molecule, the oxidation numbers must balance out to zero.
In N2O, the oxidation number of nitrogen (N) is +1 and the oxidation number of oxygen (O) is -2. This is because oxygen typically has an oxidation number of -2 in compounds, and since the overall charge of N2O is neutral, the oxidation number of nitrogen must be +1 to balance the charges.
The oxidation number in NO2 is +4 for nitrogen and -2 for oxygen. In this molecule, nitrogen is assigned an oxidation number of +4 because it is more electronegative than oxygen, which is typically assigned an oxidation number of -2 in compounds.
the oxidation number of nitrogen is 5
The oxidation number of nitrogen in NO is +2. This is because oxygen has an oxidation number of -2, and since the overall charge of NO (nitrogen monoxide) is 0, the nitrogen atom must have an oxidation number of +2 to balance the equation.
In the compound NO, nitrogen (N) has an oxidation number of +2 and oxygen (O) has an oxidation number of -2. This is because oxygen usually has an oxidation number of -2 in compounds, and since NO is a neutral molecule, the oxidation numbers must balance out to zero.
In N2O, the oxidation number of nitrogen (N) is +1 and the oxidation number of oxygen (O) is -2. This is because oxygen typically has an oxidation number of -2 in compounds, and since the overall charge of N2O is neutral, the oxidation number of nitrogen must be +1 to balance the charges.
The oxidation number in NO2 is +4 for nitrogen and -2 for oxygen. In this molecule, nitrogen is assigned an oxidation number of +4 because it is more electronegative than oxygen, which is typically assigned an oxidation number of -2 in compounds.
the oxidation number of nitrogen is 5
The oxidation number of nitrogen in NO is +2. This is because oxygen has an oxidation number of -2, and since the overall charge of NO (nitrogen monoxide) is 0, the nitrogen atom must have an oxidation number of +2 to balance the equation.
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
The oxidation number of nitrogen in most compounds is -1***************2nd Opinion *******************I don't think so. Nitrogen has many oxidation numbers. +5 is pretty common, as found in nitrates. +3 is found in nitrites. -3 is found in ammonia and nitrides. What is the most common? That I don't know.
The oxidation number of nitrogen in hydrazine (N2H4) is -2. This is because hydrogen usually has an oxidation number of +1, and in this case, since there are two hydrogens bonded to each nitrogen, the total oxidation number for nitrogen must be -2 to balance it out.
The oxidation number of nitrogen in NO2 is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of NO2 is 0, the nitrogen atom must have an oxidation number of +4 to balance the charges.
The oxidation number for oxygen in most compounds is -2.
The oxidation number of NO, nitrogen oxide, is +3.
Nitrogen's oxidation number is -4.Carbon's oxidation number is +3.The cyanide ion has -1 charge. Nitrogen is in -3 state. By balancing the charges: the oxidation number of carbon is +4.
